Millions of Americans are progressively losing their sight as cells in their eyes deteriorate, but a new therapy developed by researchers at the University of California, Berkeley, could help prolong useful vision and delay total blindness.

New research led by scientists at Newcastle University, UK reveals a potential revolutionary way to treat eye injuries and prevent blindness - by softening the tissue hosting the stem cells which then helps repair wounds, inside the body.

The incidence of ocular hypertension varies among by race and ethnicity, and also increases with age. According to one epidemiological study, African-Caribbean persons are more at risk for ocular hypertension; this group has the highest prevalence of disease globally (12.6%).

Keratitis is a medical term for corneal inflammation. The cornea is a clear dome of epithelium that covers the front of the eye, allowing light to pass through. It covers the iris (colored part of the eye), the pupil and the anterior chamber of the eye.

Soon, an eye examination may be all that is needed to confirm a diagnosis of Alzheimer's disease, according to researchers at Duke's Health. Duke Eye Center recently recruited and studied the retinas of over 200 individuals to see if there were any differences between those with Alzheimer's and those without.

An aqueous flare is an optical phenomenon based on light scattering within the anterior chamber of the eye. This phenomenon occurs when an inflamed eye is viewed at right angles to a beam of light shined obliquely into the anterior chamber.

Ametropia is defined as an eye disorder due to an error in the refractive power of the eye. In simpler words, the eye is unable to bend light correctly and focus images directly on the retina. This ultimately results in blurred vision.
